This invention relates to amusement devices and more particularly to acombined merry-go-round and see-saw.

An object of the invention is to provide a device of this characterwhich may be conveniently used on play grounds, beaches as well asprivate homes.

Further the invention provides an amusement apparatus whereby aplurality of persons may oscillate or see-saw and at the same timerevolve about a vertical axis.

With the preceding and other objects and advantages in mind, theinvention consists in the novel combination of elements, constructionsand arrangements of parts and operations to be hereinafter more fullydescribed, claimed and illustrated in the vaccompanying drawings,wherein:

Figure 1 is a perspective of the invention;

Fig. 2 is a view partly in vertical section and partly in elevation;

Fig. 3 is a horizontal section taken on line 2-2 of Fig. 2.

Referring to the invention in detail a base is provided which consistsof upper and lower horizontally disposed discs 5 and 6 connectedtogether by spaced vertical slats 7. The base is reinforced at its lowerend by a circumferential band 8 extending around the lower 30 ends ofthe slats and the disc 6.

A turntable 9 is revoluble on the disc 5 and carries a depending annularflange 10 which skirts the disc 5. Anti-friction elea ments such asrollers 11 are attached to the 35 under face of the turntable at thecenter of the latter and adjacent its other edge. Openings 13 are formedin the turn table above the rollers to afford clearance for the latter.These rollers 11 are revoluble on circular track ways or wear strips 14.

A revoluble post 15 passes centrally through the base and turntable. Atits lower` end Jthe post is formed with a reduced part 16 which isrevoluble in a central opening 17 in the disc 6. A key 18 extendstransversely through Serial No. 356,461.

the reduced part to hold the post against vertical displacement. Toreduce friction at the lower end of the post a bearing race 19 isreceived on the reduced part above the disc 6 and contains bearing balls2O which contact with a shoulder on the post adorded by the reduced end.

The post extends a considerable height above the turntable and is formedwith a bore or socket 21 for the reception of the shaft of a suitablesun-shade or parasol 22. In practice the post and turntable rotatetogether and for this purpose these parts are rigidly connected bysuitable angle brackets 23. These angle brackets are of such strength asto rigidly support the post.

The lower portion of the post is enclosed in a rectangular housing 23built within the base. Thus dirt, sand and other foreign matter cannotcome in contact with the bearing balls when the apparatus is used out ofdoors.

Arranged above the turntable in intersecting relation is a pair ofpassenger carrying boards or see-saws 24. Each of the boards 24 isprovided with a central rectangular opening 25 through which the post 15passes. Tnverted U-shaped hand grips 26 extend from the upper face ofeach of the boards and are located at either side of the post.

In order to pivotally support the boards shafts 27 extend transverselythrough the post and are embraced by transversely aligned bearings v23attached to the under face of each board.

In the operation of the invention the turn ments depending from theundeifaee of the disk and having rolling Contact With the base, acircular flange depending from the edge of the disk and overlying theouter edge of the base, a vertical post extending centrally through thebase and disk, means for securing the disk to the post, a bearing forrotatably supporting the lower end othe post, and passenger carryingbeams pvotally supported on the post above Jdie disk.
